yes, I think bull market has been started. Because maximum coin are pumping and this happen only bull market. I think very soon Bitcoin will go 10k over.
Its will be started but slowly not running like 2017, every rising steps have stopping price and correction like this day if bitcoin price reached $ 6200 then easily go to $ 6500..
There are many people predicting the price of Bitcoin that it will cross more than 6500$ but don't completely fix to it. There might be down and up when the price of Bitcoin is increasing. Right now the situation we have is to move according to the situation of the market which it is impossible for us to predict whether the price of Bitcoin will beyond 6500$ or below to 6000$.
